Zebra Danio Injury? Disease?

Personally I would keep him in the QT. Under the skin fish are just <coff> fish food and you don't want other fish nibbling at him. To further reduce the risk of infection I would up the daily water changes to 75% (again much easier if he is in the QT) and use aquarium salt at a dosage of 1 tablespoon per 10 litres. Dissolve this in water before adding to the tank. When you do a water change only add enough salt for the water you are replacing. Keep him in the salt for 2 weeks and then stop adding salt when you do the water changes.

Thanks for your reply. Since adding him into the main tank his colours are back to normal and seems so much happier. I'll keep a close eye on him for the next few days, if I see no progress I'll put him into quarantine tank again and will do what you suggest, thanks.

Very nice to hear that he is getting back to normal!

If it is an ulcer (which fits with the fish being in this condition for sometime), Melafix and aquarium salt are good options. Salt dosed at 1 heaped tablespoon for 20 litres of water would be safe in the main tank if you wanted to treat him in there. If the ulcer deteriorates you could go to the higher salt dose or treat with formalin.
Post again if his condition changes.

Thanks, I'll update you in the coming days

Update: I had to pull it out the main tank after that day, the males were in breeding mode so it kept being chased, worried that the wounds were going to be picked as Naughts suggested so I put it back into quarantine, I've been doing a 40% water changes each day & I've been dipping it into Methylene Blue each day too, as I don't have aquarium salt just yet. It still has the wounds (I've attached a decent picture of it) it's much more pale than usual as it's just come out of being in a dip. It's swimming as if it's got weight to the body that keeps dragging it down, but still swims completely fine when spooked & it's eating completely fine still.

I noticed a white fuzzy spot on the top wound today, it got brought up earlier in the thread so pointing it out, cheers
